So you have two trained, experienced former Tal Shiar members who are loyal to you and willing to put their lives at risk for you. They also have expert knowledge of Romulans and specifically know much more about the super-duper double secret Zat Vash than your ordinary run of the mill Romulan...

... and they have some really amazeballs gadgets! Like 28th century tech that can 're-create' the contents and events of a room and project it holographically...

... so, you're off on an adventure that will invariably bring you into conflict not just with Romulans, the Tal Shiar but also the Zat Vash...

... logically you ask this pair of highly trained, motivated, experienced, knowledgeable, able and equipped... to stay and mind your winery and take care of your rescue.
